SPECIFICATION forming part of Letters l atent No. 291,016, dated January1, 1884:. Application filed May 7, was. (No model.)

- To all whom it may concern.-

Be it known that I, HIRA'M R. ADAMS, of

setts, have invented an Improvement in Apparatus for Operating upon theUppers of Boots and Shoes, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention has for its object the production of an apparatus to rubagainst and fit the upper of a boot or shoe to a last or form on whichthe said upper is held stretched, and is applicable in crimping,lasting, and treeing.

In my invention as herein embodied I employ two rubbing-wheelslocated,when in use, each atopposite sides of the last or form, and rotated inopposite directions, the axes of the said rubbing-rollers being held orcarried by arms made movable with relation to each other under thecontrol of the operator, whereby he is enabled to keep the said rollersin contact with the upper, notwithstanding variation in the shape of theform, and to cause the said rollers to act upon the upper with more orless friction or stress, according to the material being operated uponand the extent to which it is desired to stretch the same, making thesaid material conform closely without wrinkles to the shape of the form,the stretching and fittingbeing from the center line of the top of theform toward the edges of the upper.

My invention consists, essentially, in an organized machine forstretching, fitting, and shaping an upper to a form, it containing tworubbing rollers and means to rotate them simultaneously in oppositedirections at opposite sides of thepform, whereby the upper is actedupon at opposite sides of a central line drawn longitudinally throughthe foot of the form, and by a force exerted from the said central linetoward the edges of the upper.

Figure 1, in side elevation, illustrates an apparatus embodying myinvention. Fig. 2 is a front View of the main part of Fig. 1, and Fig.3is a diagram of the belts for moving the rubbing-wheels.

The standard A at its upper end supports a weighted or counterbalancedlever,B,having at its pivotal point a driving-pulley, O, and to thefront end of the lever is pivoted the pendant D,

which supports the rubbing devices to be described. The pendant D,pivoted at-4on the lever B, has a short shaft, 1), to which at one endis attached a belt-pulley, b, about which is passed the maindriving-belt b extended over the two I sheaves23, and about the maindriving-pulley O. The shaft b has attached to it, at the op posite sideof the pendant D. a second beltpulley, b and an idle-pulley, I)", placedloosely 6Q on the said shaft at the side of the fast pulley b This shaftb also serves as the fulcrum for the two hand or bearing levers or arms0 c, each,as herein shown, at its lowest end being provided with ahandle, and with a forked 6 part, '0, and with a shaft, (1. Each shaftdhas attached to it a rubbing-wheel, e, and a beltpulley, e, whichreceives an endless belt, e, extended about the two pulleys e on theshafts d, and also about the two idlcrs f f and g g, 0 one idler f andone g being placed loosely side by side on studs h, attached to ears ofthe pendant. The belt 6* is also passed under and about the fast pulleyb and the sheave b,

before described, the belt 6 deriving its motion from the pulley b, andturning the shafts d and rubbing-wheels ein opposite directions to eachother, as indicated by the arrows thereon, so that the saidrubbing-wheels act on the upper m on the form n in the direction of thearrows 8, Fig. 1, or from a line drawn through the center of the uppertoward its edge, or in aline toward its edge from any point of the lineincluded between 10 and 12. The pendant D has a joint at D, to permitthe lower portion of the same, which carries the shaft b and parts belowit, to be turned or swung up about the said hinge, to enable the rubbersto follow the curved line of the foot, the lever B, a forked lever ofusual construc- 0 tion, being atthe same time turned about its pivot a.Idlers or belt-tighteners 1) act at each side the belt D to hold it onthe pulley b when the lower part of the pendant is turned on the hinge.The pendant has a joint at 19 5 by which the lower part of D and itsattached shaft 6 may be turned about a vertical pivot or axis.

The rubbing-wheels may be made to act more or less powerfully upon theupper by turning the levers c c, and applying to them more or lessforce, and the said rollers may have either plain or corrugatedsurfaces, and be more or less hard; or, instead of the rollers, I mayuse brushes. Preferably the studs 71, holding the sheavesf y, will bemade adjustable to enable the belt to be kept taut.

I claim 1. In a machine to act upon an upper on a form or holder, tworotating rubbers adapted to bear against the upper'at opposite sides ofthe form or holder, and having rotary movement simultaneously inopposite directions, whereby the upper is simultaneously rubbed at bothsides from its center line outward to ward its edges, substantially asdescribed.

2. Thetwosi1nultaneously-rotatablerubbers and levers to sustain theirshafts and regulate the pressure of the rubber against the article to berubbed, combined with a movable pendant, and with means, substantiallyas described, to rotate the said rubbers.

3. The pendant and its driven shaft I), combined with the two shafts dd, the two pulleys c, the pulley I), idler I), and the two idle pulleysor sheaves ff 1 r combined with the end less belt 6", arranged asdescribed, to simultaneously turn the two shafts d and their attachedrubbers in opposite directions, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
